#117 Support for reporting bugs from certain error messages

[Thomas Friedrichsmeier]

a) Improve the existing report-bug facility to also provide info at least on frontend version and OS, in case the backend is unavailable.
b) Implement an error dialog that has a button to invoke the report-bug facility (including the error message/id).
c) Use that for common reportable error conditions.

See http://www.mail-archive.com/rkward-devel@lists.sourceforge.net/msg02054.html .

[Thomas Friedrichsmeier]

a), b): Implemented.

c) For now b) is used for the "Backend has died" message(s), only. Ideas for other messages that we want to encourage reporting?

Implemented in 0.6.2.
